=== Operational data collection and analysis ===
Operational data is data that z/OS system produces when it runs. This data indicates the health of the system and can be used to identify sources of performance and availability issues in the system. IBM Z Operational Log and Data Analytics and IBM Z Anomaly Analytics with Watson collect IT operational data from z/OS systems, analyze and provide insights about the operational data.

IBM Z Operational Log and Data Analytics collects IT operational data from z/OS systems, transforms it to a consumable format, and streams it to third-party enterprise analytics platforms like the Elastic Stack and [[Splunk]], or to the included operational data analysis platform. The included insights can help to visualize and search operational data to help identify the cause of operational issues.<ref>{{cite web |url=https://www.ibm.com/products/z-log-and-data-analytics |website=IBM |title=IBM Z Operational Log and Data Analytics Product Page|date=16 May 2024 }}</ref>

IBM Z Anomaly Analytics with Watson collects IT operational data from z/OS systems, uses historical IBM Z metric and log data to build a model of normal operational behavior, then analyzes real-time operational data through comparison with the model of normal operations to detect anomalous behavior, and notifies IT operations of the anomalous behavior to identify incidents that might lead to business disruption.<ref>{{cite web |url=https://www.ibm.com/products/z-anomaly-analytics |website=IBM |title=IBM Z Anomaly Analytics with Watson Product Page|date=27 June 2024 }}</ref>

==== Operational data types ====
IBM Z Operational Log and Data Analytics collects and analyzes both structured and unstructured data, including the following types of operational data:<ref>{{cite web |url=https://www.ibm.com/docs/en/z-logdata-analytics/5.1.0?topic=overview-z-common-data-provider |website=IBM |title=IBM Z Operational Log and Data Analytics documentation}}</ref>

* [[IBM System Management Facilities|System Management Facilities]] (SMF) data
* Log data from the following sources:
** Job log, the output which is written to a data definition (DD) by a running job
** z/OS UNIX log file, including the UNIX System Services system log (syslogd)
** Entry-sequenced Virtual Storage Access Method (VSAM) cluster
** z/OS system log (SYSLOG)
** IBM Tivoli NetView for z/OS messages
** [[IBM WebSphere Application Server]] for z/OS High Performance Extensible Logging (HPEL) log
** z/OS Resource Measurement Facility (RMF) Monitor III reports
* User application data, the operational data from users' own applications

IBM Z Anomaly Analytics with Watson collects data from multiple IBM Z systems and subsystems, including [[IBM Db2]] for z/OS, IBM CICS Transaction Server for z/OS and [[IBM MQ]] for z/OS.<ref>{{cite web |url=https://www.ibm.com/docs/en/z-anomaly-analytics/5.1.0 |website=IBM |title=IBM Z Anomaly Analytics with Watson documentation}}</ref> The following types of operational data are collected: 
* [[IBM System Management Facilities|System Management Facilities]] (SMF) data
* z/OS system log (SYSLOG)
